SOHA II Builders Thread - Page 3

I used wiatrom's drill template for the bottom, and added top / side vent holes like this, and it gets a little warm, but nowhere near hot. The nod is toward Holland's case, where the bottom and top vents seem quite adequate, or a vented top / bottom as runeight aluded to. This is with all stock BOM except Auricap on c1.

The case I used does have vents on both sides of the enclosure + the two 1” diameter tubes holes on top, while the 2 tubes are actually located outside the enclosure (air-cooling). Moreover, the heater voltage regulator (in high current mode) is mounted directly on the 3mm thick aluminum enclosure, which serves as a large heatsink. The amp does get hand-warm in the long run, but never warmer than body temperature.

I miss the amp a lot since my GF took the amp to her office.

I've just spotted a part number error in the UK BoM I sent to Alex which is hosted on the website

The E12 Relay (component K1E) , the Rapid part no. reads 60-0432 - it *should* read 60-4032

Thanks Uncle Bob. I'll fix this.

How's your SOHA II doing?

Not so good I still haven't received my board, it's looking like its been lost in transit. If it hasn't arrived by this weekend, I'll have to order another one from Jeff

Don't worry, that is a good reason for me to put this amp into this enclosure ASAP.

Anybody listening to the II with Denons? At our mini-meet, we again noticed the particular synergy of the II with all Sennheisers.

With Denon 7000s, the II significantly lifted the soundstage, brightened the mids and highs and seems to decrease the bass. Very interesting...

IIRC, Postal_Blue did his entire review of the II with Denons. I can't find that link at the moment, but I'm pretty sure that he did.
